Аннотация: Regularities of sorption extraction of platinum(II, IV) and rhodium(III) by anion exchangers of various physical and chemical structure in the presence of hydrochloric media were studied. It is established that AM-2B, Purolite A 500, and Purolite S 985 ionites adsorb complex anions of platinum metals employing mixed mechanism. A high affinity of the studied anionites for the studied complex anions of platinum and rhodium is established.

extraction pyrolytic method -- luminescent films -- X-ray diffraction -- luminescence spectra
Аннотация: Luminescent Y1.74Eu0.16Bi0.1O3 films have been obtained by extraction pyrolytic method. The formation of a crystalline structure in the film upon isothermal annealing in air at 600–650°C was established by X-ray diffraction. Single-phase Y1.74Eu0.16Bi0.1O3 films begin to exhibit luminescent properties after pyrolysis at 500°C; the intensity of luminescence increases with increasing temperature. The films annealed at 800°C consists of defect-free homogeneous crystallites with sizes of about 0.7 μm and demonstrats high luminescence intensity.

platinum -- iron -- ionites -- sorption -- hydrochloric solutions -- sorption
Аннотация: The sorption concentration of platinum(II,IV) in the presence of iron(III) is studied on new samples of domestically produced ionites of the CYBBER brand. In comparing the sorption and kinetic properties of the new ionites to those of sorbents of the Purolite brand studied earlier, the higher effectiveness of the former is demonstrated via the extraction of platinum(II,IV) ions from strongly and weakly acidic chloride solutions. It is found that the sorbed platinum ions can be completely separated from iron(III) ions through separate elution using 0.01-0.001 M HCl (iron ions) and a thiourea solution (80 g/L) in 0.3 M H2SO4 (platinum ions).

    Transparent conductive ITO coatings obtained by pyrolysis of metal extracts / T. N. Patrusheva [et al.] // J. Appl. Chem. Sci. Int. - 2015. - Vol. 3, Is. 1. - P. 21-28 . - ISSN 2395-3705

Indium-tin oxide -- thin films -- extraction-pyrolysis technique -- liquid precursors -- nanocrystalline structure
Аннотация: Thin films of indium-tin oxide (ITO) have been prepared by pyrolysis of liquid organic-extracts of indium and tin. The films were deposited on glass substrate in the atmospheric condition. Extraction-pyrolytic method adopted here uses cheap starting materials and provides the required stoichiometric ratio by mixing the stable liquid precursors in appropriate concentration. Thermal decomposition processes are induced in the narrow temperature range of 350–400°C. The zirconium-yttrium oxide (ZYO) sublayer was deposited on glass substrate in advance to provide homo epitaxial growth. This would induce reduction in intrinsic stress of the films due to matching in thermal expansion coefficient with ITO film. XPS studies showed the absence of impurity elements in these extraction-pyrolytic technique derived ITO films and the spectra is quite similar to that for ITO films deposited in vacuum environment. ITO film has a nanocrystalline structure with grain size of about 6 nm.

Аннотация: We have experimentally studied the magnetic properties of manganite films obtained for first time using an extraction-pyrolysis technique. It is established that the characteristics of samples significantly depend on the conditions of final annealing. The annealing at temperatures T-a 970 K is accompanied by strong thermomagmetic effects. and the resulting films possess properties similar to those of spin glasses. When the annealig temperature is increased to T-a = 1020 K, the films exhibit magnetic properties typical of ferromagnetic systems.

Аннотация: We consider the problem of determining the parameters for high-T-c superconducting copper oxides. Alternative approaches, the ab initio LDA and LDA + U calculations and the generalized tight-binding (GTB) method for strongly correlated electron systems, are used to calculate hopping and exchange parameters of the effective singlet-triplet model for the CuO2 layer. The resulting parameters are in remarkably good agreement with each other and with parameters extracted from experiment. This set of parameters is proposed for proper quantitative description of the physics of hole-doped high-T-c cuprates in the framework of effective models. (C) 2004 MAIK "Nauka / Interperiodica".

Аннотация: Yttrium-containing endohedral metallofullerenes are synthesized in an RF arc discharge in the helium flow with embedded Y2O3. It is shown that the formation of the metallofullerenes depends on the helium pressure in a chamber; however, this dependence cannot be explained using the model of formation of conventional fullerenes without a guest atom in a molecule. The results of extraction of Y@C-82 by pyridine and carbon disulfide are reported. The pressure corresponding to the maximum yttrium-containing endohedral metallofullerene content is shown to be 60 kPa; under this pressure, extraction by carbon disulfide allows obtaining 27.1 wt % of the endohedral metallofullerene, while extraction by pyridine yields its amount of 17.3 wt %.

solution extraction -- mechanical extraction -- fullerenes -- Soxhlet
Аннотация: The Soxhlet extraction method (SE) only used in the extraction of fullerenes from carbon condensate (CC) obtained in the fullerene production facility, which in the literature is often referred to as carbon black, does not provide complete extraction. Fullerenes can also be extracted from the CC suspension and the solvent by the mechanical extraction method (ME) and show higher degree of extraction efficiency. This method combined with filtration process takes only a few minutes and allows a significant reduction in solvent consumption. Extraction via the ME method application makes it possible to carry out extraction of fullerenes twenty times faster than by the SE method. It can be used as an independent method, bypassing the extraction by the SE method, and also as an additional one. Application of the ME method allows additional extraction of fullerenes weight percentage from the CC, after extracting fullerenes from it applying the SE method. In this instance the higher fullerenes prevail in the essences extracted by the ME method with their content reaching as high as 39.50 wt%. The obtained samples of fullerene mixtures (FM) are characterized by the methods of high-performance liquid chromatography and mass spectrometry. Analysis of the results shows that the composition of the FM, isolated by the ME method, differs from the compositions extracted via the ME method.

Кл.слова (ненормированные):
spin accumulation -- interface states -- hybrid structures -- Hanle effect -- iron silicide
Аннотация: Spin accumulation effect in Fe3Si/p-Si structure with low boron doped silicon substrate was found. Calculated spin lifetimes are comparable with results reported earlier but for structures with highly doped semiconductors (SC) with or without a tunnel barrier introduced between the SC and ferromagnet (FM). Electrical characterization of a prepared Fe3Si/p-Si diode allowed the determination of possible reasons for the pronounced spin signal. Analysis of the forward bias I-V curve revealed a Schottky barrier at the Fe3Si/p-Si interface with a height of φBp = 0.57 eV. Then, using impedance spectroscopy, we observed interface states localized in the band gap of silicon with energy of E LS = 40 meV. Such states most probably cause the observed spin signal. We believe that in our experiment, spin-dependent hole extraction was performed via the interface states resulting in the minority spin accumulation in the silicon valence band. The observed effect paves the way to the development of different spintronic devices based on FM/SC structures without dielectric tunneling barriers.
